How do you wear a blazer with a casual shirt? Match the informality of your shirt–be it a polo, henley or t-shirt–to your jacket. Choose a unstructured jacket in a casual cotton instead of your traditional wool.

You could always try the plain t-shirt under the blazer (or layered tees), but you can take the outfit up a notch by layering a fitted polo shirt over a t-shirt. Bonus points for a brightly colored tee–we love the splash of color this creates at the neckline.

Finish the outfit off with a casual belt (woven, not leather) and a pair of stylish sneakers.
